GCRA has approached the initial review of the subject plans from the vantage of Utility/User interests in an HTGR-SC/C Lead Project as characterized in the HTGR-SC/C Lead Project Plan. At their current stage of development, the plans are considered to represent the early views of General Atomic Company, acting as a potential NSSS vendor, on the effort necessary to design and license an HTGR-SC/C plant. As such, these plans embody GA's perception of the level of technical development and demonstration needed to support the cost and risk sharing assumptions in the Lead Project Plan. These plans and the plant design which they address will be subjected to a more formal review by other vendor and Utility interests in the course of establishing the Project Decision Package scheduled for June 1982. The culmination of these review activities will be the adoption of this information by all participants as the HTGR-SC/C Program Baseline.

Procedures are described for the systematic assessment of a Material Control and Accounting (MC and A) system, in terms of compliance to the proposed MC and A Upgrade Rule. The applicability of these assessment procedures to specific Rule provisions is discussed. Special attention is given to the statistical performance of individual subsystems, and their vulnerability to compromise by insider collusion.

Progress is reported in a project in which the objectives are to evaluate benefits associated with control of the surface energetic properties of materials used in heat exchangers, and to identify preferred ranges of these surface conditions that minimize deposits of biological fouling known to deteriorate heat exchange efficiencies in seawater, brackish water and freshwater systems. The technical approach employed uses special diagnostic plates in novel flow cells where fluid flow conditions can be well-controlled, modifying the surface chemistry and surface energy of the plates with very thin coatings and examining the earliest events of biofouling caused by macromolecules and microbial organisms. Information is included on exposure experiments and results and heat exchange experiments.

This analysis identifies the economic impacts associated with OTEC development and quantifies them at the national, regional, and industry levels. It focuses on the effects on the United States' economy of the domestic development and utilization of twenty-five and fifty 400 MWe OTEC power plants by the year 2000. The methodology employed was characteristic of economic impact analysis. After conducting a literature review, a likely future OTEC scenario was developed on the basis of technological, siting, and materials requirements parameters. These parameters were used to identify the industries affected by OTEC development; an economic profile was constructed for each of these industries. These profiles established an industrial baseline from which the direct, indirect, and induced economic impacts of OTEC implementation could be estimated. Each stage of this analysis is summarized; and the economic impacts are addressed. The methodology employed in estimating the impacts is described.

Econoimc profiles of the industries most affected by the construction, deployment, and operation of Ocean Thermal Energy Conversion (OTEC) powerplants are presented. Six industries which will contribute materials and/or components to the construction of OTEC plants have been identified and are profiled here. These industries are: steel industry, concrete industry, titanium metal industry, fabricated structural metals industry, fiber glass-reinforced plastics industry, and electrical transmission cable industry. The economic profiles for these industries detail the industry's history, its financial and economic characteristics, its technological and production traits, resource constraints that might impede its operation, and its relation to OTEC. Some of the historical data collected and described in the profile include output, value of shipments, number of firms, prices, employment, imports and exports, and supply-demand forecasts. For most of the profiled industries, data from 1958 through 1980 were examined. In addition, profiles are included on the sectors of the economy which will actualy construct, deploy, and supply the OTEC platforms.

The radial Fokker-Planck (RFP) model of A. Futch was modified to treat plasma buildup in the tandem mirror plug and center cell with a self-consistent model (TOARBUC). Two major changes have been made to the original version of this code. First, the center cell is treated as having separate electron and ion confining potentials with the ion potential having the opposite sign of that in a conventional mirror. Second, a two-electron-temperature treatment derived by R. Cohen was included in the present model to allow the plug and center cell to have different T/sub e/'s as observed in the experiment. The following sections explain these changes in greater detail.
